HospitalizationMilestone

Marks the kind of hospitalization event, as used in the Hospitalization fact.

These are:

  • a Discharge, with no admission in the temporal component,

  • an Admission, with no milestone in the temporal component,

  • or a hospital Stay, in which the temporal component has a begin and end associated with admission and milestone.

For example, if the event of interest is the discharge date _as well as length of stay, the Stay variant should be used, with length of stay represented as the duration of the temporal compoenent whose end-point is the discharge time.

Each of the three kinds of events can optionally hold Text data, which should be used to represent information such as discharge status. In the future, we might make this more detailed by providing a separate HopsitalizationMilestoneData fact, say, which is a record type with multiple fields.

MedicationMilestoneData

The MedicationMilestoneData fact may be used to provide information for a single MedicationMilestone event.

"amount" refers to the amount of medication issued in the medication milestone. The amount of the medication has two components. The first represents the value, which can be either a text or a number. The value refers to the amount of medication in one discrete unit of the medication. The second represents the units associated to the value, which are text.

"route" refers to the delivery mode of the medication issued in the medication milestone. Some examples would be "intravenous", "oral", etc.

"dose_number" refers to the position of the medication milestone dose in the sequence of all medication milestones doses.

"days_supply" refers to the number of days of medication issued in the medication milestone.

"strength" refers to the concentration of the medication issued in the medication milestone.

"quantity" refers to the number of discrete units of medication issued in the medication milestone. So, for example, the number of pills in a bottle of prescription medication.

In general this fact should be used within the MedicationMilestone fact. The code identifying the kind of medication would be put in a code fact, if relevant, wherever the MedicationMilestone fact is used.
